Testimonial

What our patients say

My father recently underwent gallstone surgery under the care of Dr. Sonal, and we are extremely grateful for the wonderful treatment he received. From the very first consultation, Dr. Sonal was patient, approachable, and explained everything clearly, which gave us a lot of confidence. The surgery was carried out smoothly, and my father's recovery has been very comfortable, thanks to the doctor's expertise and guidance. Dr. Sonal also gave personal attention post-surgery, ensuring that all our queries were answered and that my father felt cared for throughout the process. We truly appreciate his professionalism, kindness, and dedication. I would highly recommend Dr. Sonal to anyone in need of surgical care.

Astha Bharti Patient's Daughter

I have been to Ruban hospital for my father's surgery wherein I got in touch with dr Kumar Sonal . And I am very greatful to him as the whole surgery was successfully executed. I would like to thanks dr Kumar Sonal as he is very down-to-earth with his patients , treats patients like his own family members, always available for patients and their concerns. Thus I would like to give him 5 star for his professionalism.

Amit Singh Patient's Son

I recently underwent a laparoscopic transabdominal pre-peritoneal (TAP) mesh repair performed by Dr. Kumar Sonal, and I want to highlight the exceptional care and expertise provided. Dr. Sonal's professionalism and skill were evident throughout the entire process, from the initial consultation to the post-operative follow-ups. The surgery was conducted seamlessly, and I felt reassured at every step. However, it's important to note that the procedure was relatively costly. While I understand that quality healthcare comes at a price, it's a consideration for those on a budget. Despite this, Dr. Sonal's thorough explanation of the procedure, clear communication, and the overall positive experience have made the investment worthwhile. The supporting staff at the facility were also commendable, contributing to a positive overall experience. The facility itself was well-maintained and conducive to a comfortable recovery. I am now well into my recovery, and the results are beyond my expectations. I recommend Dr. Kumar Sonal for those who prioritise quality care. Thank you, Dr. Sonal, for your dedication to your patients' well-being.
